Question

determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. letter grades in a math course. choose the correct level of measurement. a. interval b. ordinal c. nominal d. ratio

Explanation:

Letter grades (e.g., A, B, C, D, F) have an order where A is better than B, B is better than C, etc. But there is no consistent interval between them (the difference between an A and a B isn't a fixed numerical value like in interval - scale data), and there is no true zero. So, they are ordinal - scaled.

Answer:

B. Ordinal
